As the saying goes, there’s only a half-dozen or so original ideas out there, and everything else is just a variation on them. Of course, every now and then Hollywood screenwriters also steal from one another, and you end up with two studios doing essentially the same movie at the same time. Remember the dueling killer meteorite movies from 1998 aka Michael Bay’s “Armageddon” and Mimi Leder’s “Deep Impact”? For some reason, 2010 is shaping up to have a record number of dueling, similarly-themed projects.

Sure, it could all be one big coincidence, and maybe my aunt Selma is really the reincarnation of Cleopatra…
